I believe it’s going on a street car.


Be curious to see that motor go down the track. Sounds extremely optimistic to me, especially based on other trick flow stuff that has went down the track i know about. Thats pretty much saying it would make 630-640 with compression.
That’s healthy W5 type power.


Track times don't mean much, especially for street cars or novice bracket racers. Lots of street cars have 10 second power but 12 second tires. I don't have any trouble accepting that TF heads on a 400 inch SB Mopar can make 600 hp. Just because nobody at your track runs 9's with a TF headed SB doesn't mean it isn't possible.

The 700 hp LS7 with a small cam is a different animal. That number isn't what I'd expect from that cam.


I didnt say it wasn't possible. But its very unlikely with a very mild street roller and low compression. Not talking street cars or “ novice” bracket cars.
To clarify, a dyno can say anything. Lets just say i wouldn't believe such numbers until i saw some MPH numbers at the track, and leave it at that. Such numbers i have yet to see at the track.
